Upgrading Big 3 + Alternator???

Question

If I upgrade the "Big 3" with 2 guage wires for a 1500w rms amplifier.

Will a 160 amp alternator be good enough? I want to find a HO Alternator and this is as high as I could find for a Jeep Cherokee

Answer 1

too many amps for a 2 gauge wire imo.

just go with 1/0 gauge wire from the start man. there will be much better current flow. also, add a fuse to the powe wire that will be running from the battery + to the alternator. if the alternator or any other big3 source already has wires, just add the new 1/0 wire to it.

ive had some customers that just love showing off the thick 1/0 cable too lol. the cheapest you can find 1/0 cable online that is true 1/0 is for around 1.75 US bucks . very cheap imo.

Answer 2

that sound be fine to start with

make sure you fuse the alt wire have seen some that wave had problames if they didn.t

Answer 3

You should be able to get by with a 160A alternator.  

You should look into upgrading to a deep cycle battery (if you haven't already).  Then you should be all set upgrading your charging system.

Good Luck!!!

Answer 4

check around at some local shops. i got my alt. rebuilt from 120a to 180a for under $200....i just told them to go as big as it could.
